Abstract
An excavating tooth point (27) comprising a relatively elongated body having an earth engaging forward end (22) and a socket (36) extending forwardly from a rear end thereof. A pair of spaced apart, aligned openings (37, 38) in said point communicates the exterior of the point with the socket for receiving a pin (31) releasably securing the point to an adapter.
A cavity in the point communicates with one of the openings in the point, the cavity being defined by upper and lower walls connected by a vertical wall. A resilient lock (32) is mounted in the cavity and projects into one of the openings in the point.
The lock is supported only by the point prior to engagement with the pin in the opening.
A cavity in the point communicates with one of the openings in the point, the cavity being defined by upper and lower walls connected by a vertical wall. A resilient lock (32) is mounted in the cavity and projects into one of the openings in the point.
The lock is supported only by the point prior to engagement with the pin in the opening.
